Dotnet / Package Dotnet Application Single File

Package Dotnet Application Single File

Packages a .NET application as a single file for distribution.

$
Terminal
dotnet publish -r <runtime_identifier> -p:PublishSingleFile=true <path/to/project_file>

When To Use

In scenarios where compact deployment packages are necessary for distribution efficiency.

Pro Tip

Test the single-file output rigorously, as extraction might affect assembly loading due to filesystem structure.

Anatomy of Output

Troubleshooting

Common pitfalls

NETSDK1045: The current .NET SDK does not support targeting 'your-runtime-id'.

Solution: Ensure SDK is aligned with your specified runtime.
